Ok so I read this thread and was hoping this would work. But I tried it yesterday and it didn't. Here are the steps i did, please take a look and see if I did something wrong.

Background: 2013 Focus SE Hatch, bought for my daughter for college, only came with one key and it was a mykey. I purchased the elm hs/ms-can device from Amazon and downloaded Forscan and Focccus. Tried Forscan first on car to make sure things communicated and everything was fine.

Steps I did:

1, Pluged ELM device into obd port, turned key to on and loaded focccus. Device left in HS-CAN position.
2, Had focccus read BCM, saved baseline to file.
3, Changed mykey input from 2 to 0. Wrote to BCM.
4, Turned car off, waiting a min, disconnected elm and turned key back to on.
5, Turned car on, said "Normal mode" on screen but still recognized mykey key and still had limitations.
6, Checked settings and it still showed 1 mykey, 1 admin key. So based on setting it to 0, the BCM didn't remove the feature.
7, Plugged ELM back in and loaded Focccus, read BCM, confirmed it was set 0.
8, Set mykey flag to 1, wrote to BCM. Repeated step 4.
9, Same as step 5. No change.
10, Did step 7 again, loaded baseline bcm program and put back loaded back to BCM.

So does anyone see anything I did wrong? I was using this a trial run because I wanted to see if Focccus worked on her car because I want to do the fog lamp install because I have the fuse 75 with a 15 amp in it.

I think you should try it all again, perhaps change the order. Because I purchased a Chinese copy obd ii device I also had a couple attempts that didn't work as intended. Eventually it did work. I suggest keeping at it.

Also, buy some extra key fobs on eBay and find a local locksmith with the computer key programmer.

If you were using focccus you can't select the incorrect bus. If you have the switch on high when it needs to be low it will tell you, and vice versa.

Do you have a key fob or an actual key? Mine is a fob with a high security key. The actual key is only to emergency unlock the driver's door. You can buy a fresh key fob for $300 at the dealership or $65-80 on eBay. Locksmiths can rarely do anything with systems like mine so make sure they know your exact model, not just that it's a whatever year focus.

The end result of writing to the BCM to remove mykey will be that mykey will disappear from the options screen and therefore your key fob will become a master.

Set it to "0", and flash. Once that's done, get out of the car and lock it. Wait a min and get back in. The MyKey option should no longer be available when you turn the car back on and go through the menus. When you set the value back, MyKey will reappear but will have been disabled.

Somehow my car has been set to the MyKey settings which limit speed to 80mph and alert you at 75mph. Not a huge deal except there's no hysteresis used. 75mph and I get an alert, slow to 74 and go back to 75, get another alert, on and on and on. Kind of annoying.

I only have one key for the car. Maybe it was like that when I bought it. Don't know, just been living with it for so long I've forgotten. The key I have apparently isn't an Admin key as it won't allow me to turn it off. So I guess I'm dealer bound? ...... which means I'm just living with it because ZERO chance I'm paying the dealer $100 for 30 seconds to clear it.[]

I suggest you try it.
I bought my 2012 focus with 1 key and the auto start fob. It had mykey enabled and I was governed at 130 until yesterday. I started the car with the FOB and went into settings and was able to clear all keys. I know it should not be able to do that, but I know I can go 140 now and all keys are cleared. so suit yourself.

yes, you seem correct about the FOB. It seems to be a power code accessory which is genuine ford. I found the manual here machenry.com/documents/Installation%20Instructions/RMST_System_Diagnosis_Guide.pdf I have the 'G' one way FOB.
In response to the 130 km/h limit. It was in fact, limiting the top speed of my focus. I get a red 'I' and a warning that my vehicle is near top speed and it wont go faster than 130. Now that the mykey settings are cleared I have been up to 140 KM/h with no warning.

Hello everyone, I wanted to post because I am so happy i finally DISABLED MYKEY! (WITH ONLY ONE KEY!!!)

I have to say, I would have never tried this or thought of this, if it wasn't for this Thread, and @novus in particular.
So thanks guys.

Okay, so i just bought a pre-owned 2016 Focus ST from a local Ford Dealership and it only came with one key. After a week of owning, I accidentally enabled the MyKey feature, not knowing what it actually was lol. (Big mistake)

So I searched everywhere for a way to disable this feature, preferably without having to buy a new key from the dealer.

1. So first things first, you need to install that application to your laptop.

2. If you purchased the same OBD Scan tool as i did, you will need to install it's drivers on to your computer. They can be found on the website listed on the instructions sheet it comes with ( You will ONLY need the drivers. Not the application the Scan tool is made for.)

3. Once you have the that done, your computer should be able to communicate with the OBD-II cord. Now you will go to your Focus, get in and close the door. DO NOT start car, just tap the ON button without pushing in the clutch or brake (Accessory Mode). Plug in your OBD-II to the car under the driver side dash and usb in to the computer. Load up the FoCCCus App.

Click the "Open" button

Now Click "Read from BCM"
There will be a progress bar on the bottom of the screen and the the FoCCCus app will read your car's ECU to get all the correct values.

4. Once done, I advise waiting about 30 seconds before unplugging the OBD-II from the car. Then turn off the car. Open and close the door to ensure it is off.

(Your car will start throwing you a number of random error codes on the screen, and give check engine light and every other kind of light. This is just part of the process and will need to be cleared later.)

5. Now you are ready for the last part. With all the value you uploaded into the FoCCCus app, scroll down to #239 MyKey. When i did it, the value was set to "2". You should click and change the value to "0".
Once you change it to "0" you can plug it back in to the car and follow the previous procedure (Put car in accessory mode). Then click "Write to BCM"
This will make you car have 0 MyKeys.
After, you will have repeat the process but this time changing the value of #239 to a "1" and rewrite it to the BCM, which will turn off The MyKey feature!
(WITH ONLY 1 KEY!!!)

To clear the error codes and check engine light afterwards, you can either use a Cobb access port, a SCT tuner, Forscan application, or have Autozone/Advanced Auto Parts do it for free.

Hope this helped!
I wanted to post this to back @novus 's claim. It really works! Even tho my dealer told me "it can't be done".

So the 2015 model year, my build date late December 2014, has the 5yr 60K warranty on the clutch packs & seals?
I'm sure the info is out on the site somewhere but can only find ref's to a 14M01 'sticky' for clutch packs & seals.

Hi,
I had a slightly damaged rear right door on my 2015 SE, and today installed a door assembly from a 2012. Everything was plug and play, but now even when the door is closed, the car thinks it's ajar. Anyone have an idea why?
Thanks,

Gave this topic a new title/thread so others might see it. I have a plain jane 2016 SE. The DTC transmission shifter only had PRNDL - with "L" being low. Using an OBDLink MX and FORSCAN (you can also use FOCCCUS), I added Sport mode (PRNDS).
Now my shifter only has the button to enable...

Does anyone know if it is possiable to take off the stock cloth headrest cover i have been looking online on how but i havent found anything. I have taken the headrest out of the seat but it seems as if it was slipped on then stitched shut.
